Specification of Letters Patent.

Patented J an. 12, 1915.

Application filed July 3, 1911. 8erial No. 633,643.

To all whom it may concern Be it known that I, WALTER E. ROBERTS, acitizen of the United States, residing at Allentown, in the county ofLehigh and State of Pennsylvania, have invented new and usefulImprovements in Hobnails, of which the following is a specification.

My invention relates to nails and more particularly to the type whichare called the hob-nails.

An object of my invention is to provide a hob-nail which is preferablyadapted to be used in connection with shoe soles and one vhich willprevent the slipping of the wearer.

Another object is to provide a hob-nail which is of such construction asto enable the same to be driven with the tools which are now ordinarilyused by mechanics.

A still further object of my invention is to provide a hob-nail which issimple in construction, efficient as a retaining means and one which isinexpensive to manufacture.

\Vith the foregoing and other objects in view my invention relates tosuch details of construction and in the arrangement and combination ofparts as will be hereinafter fully described and specifically pointedout in the appended claims.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts, and in which Figure 1 is a side elevation of myhobnail. Fig. 2 is a. sectional view of my improved nail. Fig. 3 is atop plan view of my nail. Fig. 4 is a side elevation of my nail showingone end flattened as a rivet.

In the drawings I have shown my improved nail having a tapering shank 1which is adapted to be driven into a suitable support such as thebottomportion of a shoe. Formed on one end of the shank are the offset portion2 and enlarged head 3. The offset portion 2 is adapted to engage theshoe bottom or support after the shank has been driven into the same.

The wear-head or member 4: is adapted to be retained in the enlargedhead 3 as clearly shown in Fig. 2 of the drawings, so that it projectsbeyond the lower portion of head 3, or in other words, is subjacentthereto when in use. The nail proper is preferably made of soft metalprovided with a recess in its enlarged head, into which rewhereby itresists sliding of the shoe in.

material such as culm.

As stated, the nail proper is preferably made of soft metal. Thewear-head i is made of a separate piece therefrom so that the same canbe made of metal having a greater resistance to wear than the head 3.Said head l is preferably made of steel. By forming the head l of ametal that will resist wear more than the metal of the head 3, thelatter will not wear away at its end when the person having a shoeprovided with hob-nails constructed according to my invention, walksupon a hard surface such as stone.

As stated, the nail proper is preferably made of soft metal. Theprojecting member 4 is made of a separate piece therefrom so that thesame can be made of a metal which will not wear as quickly as the metalof the nail proper, or more specifically its head. Said member 4 ispreferably made of steel. By this construction of the pro jecting memberbeing of a metal that will resist wear more than the metal of the headof the nail, the nail head will wear away. There will always be aprojecting portion of the member 4, inasmuch as the nail head will wearaway in excess of the extent to which the projecting member 4 will wearaway.

It will also be seen that my nail may be used as a rivet as shown inFig. 4.

From the foregoing it is made manifest that I provide a hob-nail which,having wear-head 4 will resist wear upon a hard surface such as stone,while the head 3, having considerable lateral surface, will resistsliding of the shoe it is carried by in fine condensed material such asculm, and hence, it may serve and enable miners to obtain a goodfoothold in and about mines where the material encountered is of suchnature.

I desire it to be understood that slight changes in the construction maybe resorted to without departing from the spirit of my invention,provided such changes fall within the scope of the subjoined claims.

Having thus fully described my invention,
